It would surprised me if he didn't.
Catcher affects OAV.
Dude has pitches that are 72, 80, 46. Forget the vL or vR, if he's getting a catcher below the recs, he's getting killed.
A catcher with 80something pitch calling will make a starter with high control, Vl Vr in the 50s, and high pitch numbers (like 90,70,60,40, or something like) probably half a point in ERA better than someone in the 50s.
